Peita ārai-waikura
Ko te peita ārai-waikura he momo matū e mahi ana hei ārai-waikura, hei ārai i te waikura whakarewa, hei whakapai ake hoki i te pānga tiaki o te kiriata peita ki te mata whakarewa. Ka taea te wehewehe i te mahi a te peita ārai-waikura ki ngā wāhanga e rua: te ārai-waikura ā-tinana me te ārai-waikura matū, ā, ka taea te wehewehe i te peita ārai-waikura matū ki te aukati waikura me te mahi hikohiko tuarua. Ko ngā matū e mahi ana hei ārai waikura ko te paura whero māwhero, te paura rino whero, te paura titanium rino hiato, te paura konumohe tripolyphosphate konutea me ētahi atu. I tēnei wā, ko te peita ārai-waikura te nuinga e whakamahia ana i roto i ngā paninga ārai-waikura, ā, ko te utu o ngā paninga ārai-waikura he 6%-8.5%.
He aha te rerekētanga i waenga i te peita ārai-waikura me te peita?
Ko te peita ārai-waikura he momo peita ka taea te tiaki i ngā mata whakarewa mai i te waikura matū, hikohiko rānei o te hau, te wai moana, me ētahi atu. He peita ārai-waikura ā-tinana, ā-matū hoki, pērā i te rino whero, te paura konumohe, te peita ārai-waikura karāte, te mata whero, te konutea kōwhai, me ētahi atu.
Ko te peita he ranunga matū e pania ana ki te mata o ngā mea, e tiaki ana, e whakapaipai ana, e tohu ana me ētahi atu kaupapa motuhake, ā, e hanga ana i tētahi kiriata totoka e piri pūmau ana ki te mata o ngā mea, ā, he kaha, he pumau tonu.
1. Ngā mahi rerekē:
He āhuatanga ātete-waikura, ātete-waikura hoki te peita ā-waikura, he pakari te kiriata, he tino pai te mahi, ā, he nui ake tōna pakeke i te peita noa. Kāore he mahi ātete-waikura a te peita noa, nā te mea he kapia alkyd te rauemi kiriata peita noa, ā, nā te waikura me te whakamaroke, he iti te pakeke, he āputa piri.
2. Te roa o te ratonga:
Ka taea te whakamahi i te peita ārai-waikura mō te 5-8 tau mēnā he ōrite. Ko te peita noa ka whakamahia ki waho mō te 3 tau pea. I muri i ngā tau e rua, e toru rānei, ka ngāwari te taka, te memeha, me te paura.
3. Ngā momo rerekē:
Peita ārai-waikura: peita ārai-waikura phenolic, peita ārai-waikura alkyd (whero rino, hina, mata whero), peita ārai-waikura rapa chlorine, peita ārai-waikura epoxy (peita ārai-waikura konutea phosphate, peita ārai-waikura mata whero, peita ārai-waikura whai konutea, peita ārai-waikura rino whero), me ētahi atu
Peita: He momo peita maha ngā momo peita, he momo peita anō hoki te peita ārai-waikura, hei tāpiritanga ki te peita kei roto hoki ko te peita rakau, te peita papa, te peita pakitara o waho, te peita kōhatu, te peita maha-tae, te peita konumohe koranu, te peita ātete ahi, te peita rapa me ētahi atu.
E waru ngā huarahi mō te whanaketanga o te peita ārai-waikura ā muri ake nei
- Tuatahi, ko te whakawhanaketanga o te peita waikura me te peita o runga mō ngā hanganga maitai.
Me whakaoti e te paninga wai-ā-waikura te raruraru o te "waikura tere" me te ātete wai ngoikore, ā, ko te putanga mai o ētahi paninga hou kāore he emulsifier kua tino whakapai ake i tōna ātete wai ngoikore, ā, me arotahi te heke mai ki te whakaoti rapanga o te mahi hanga me te mahi tono. Hei paninga o runga, ko te nuinga o te mahi he whakapai ake i tōna whakapaipai me tōna pakari i raro i te tikanga kia mau tonu te mahi tiaki.
- Ko te tuarua ko te whakawhanake i tētahi raupapa peita ārai-waikura kore-whakarewa, he nui te ihirangi totoka.
He tino tere te mahi keri, ngā papaaho takutai moana me ngā kaupapa anti-waikura nui i roto i te mahi anti-waikura tino pakari o te paninga, ko te mākete o nāianei he mea nui ki ngā umanga ke me ngā hua kawemai. Ko ngā hua o Haina kei roto i te taumata hangarau, te kaha ōhanga, te pūnaha whakapumautanga kounga me te ingoa hua me ētahi atu āputa kaha whānui me ngā whenua ke, he uaua ki te tomo ki te mākete. Hei whakatutuki i tēnei, tuatahi, me whakapau kaha ki te whanaketanga hangarau, inā koa te whanaketanga o te primer anti-waikura kore-mata me te kore-chromium, arā, i runga i te konutea phosphate me te konumohe tripolyphosphate anti-waikura.
- Ko te tuatoru ko te whakawhanake i te paninga wai-whai-konutea.
Ko te paninga konutea kore-waro me te paninga konutea kore-waro e hangai ana ki te wai tētahi o ngā paninga roa-mahi, engari he paninga whakarewa. Ko te paninga konutea kore-waro e hangai ana ki te wai me te silicate pāhare pāporo teitei hei rauemi turanga he paninga ārai-waikura mahi teitei kua whakamatautauria e te mahi, ā, he pūmanawa whakawhanake anō hoki.
- Ko te tuawhā ko te whakawhanaketanga o te paninga ātete-waikura ātete-wera mō te whakawhiti wera.
Me whai paninga ārai-waikura ngā whakawhiti wera, he ātete wera nui, he kawe wera nui hoki, ā, me whakamaroke te paninga epoxy amino e whakamahia ana i tēnei wā i te 120°C, ā, me whai paninga maha, kāore e taea te whakamahi i runga i ngā taputapu nunui.
- Ko te tuarima ko te whakawhanake i tētahi paninga ka taea te whakamaroke i te pāmahana rūma, ā, he ngāwari hoki te pani.
Ko te mea matua ko te kimi i te taurite pai i waenga i te mahi ārai waikura, te mahi whakawhiti wera me te mahi hanga o te paninga.
- Ko te tuaono ko te whanaketanga o te paninga ārai-waikura.
He tino pai te ātete hiko o te waikura rino mika (MIO), te ātete ki te koroheketanga o te āhuarangi, me te mahi aukati, ā, e whakamahia whānuitia ana hei peita tuatahi me te peita o runga i Ūropi ki te Hauāuru.
- Tuawhitu, ko te whanaketanga o te raupapa rapa chlorinated o ngā whakakapinga paninga anti-waikura.
Nā te mea he wāhanga kotahi te rapa whai kōrote, he māmā te hanga, he ātete ki te wai, he ātete ki te hinu, he ātete ki te koroheketanga o te rangi, he whānui te whakamahinga i roto i te hanga kaipuke, te aukati waikura ahumahi me ētahi atu mara, he whānui te mākete i Haina. Heoi, nā te mea e whakamahi ana te hanga rapa whai kōrote i te CC1 hei whakarewa, ka whakangaromia te paparanga ozone.
- Ko te tuawaru ko te whakawhanaketanga o ngā rauemi ārai waikura waro kua whakarerekētia, kore-waro.
I ngā tau tata nei, kua whānuitia te whakamahinga o te raima whakapūkara waro kua whakarerekētia hei whakapai ake i tōna kaha, ātete-waenga, i roto i ngā paninga papa ahumahi. I roto i ēnei, ko te whakapūkara wai epoxy (te epoxy rānei e hangai ana ki te whakarewa) kei te tere haere te whanaketanga, e kiia nei ko te sima polymer.
